Steel grit of application:
Cleaning: peen-forming cleaning - body.they - die casting cleaning - casting peen-forming cleaning - forgings peen-forming cleaning - forgings body.they castings rust-removing steel cleaning - steel plate cleaning - cleaning - h-beam cleaning - steel structure cleaning. Derusting: peen-forming derusting - shot peening derusting - casting - forging - steel derusting rust rust - forgings except oxide skin - steel derusting - h-beam derusting - steel structure rust.
Conslidation: shot peening strengthening - heat-treated pieces shot peening - gear shot peening.
Shot peening: steel shot peening - sections of sandblasting - presented.the peen-forming - steel plates - steel shot peening shot peening.
Peen-forming: plate peen-forming - steel shot bla - sections peen-forming.
Play sand: play sand treatment.
Steel shot pretreatment: before painting processing - coating pretreatment - surface pretreatment - presented.the pretreatment - steel pretreatment - steel pretreatment - steel pretreatment - steel structure pretreatment.
Various hardness steel grit:
GP steel grit: new made - be pointed leng shape - in use process edges was soon ground round - especially suitable for the descaling and surface preparationg applications.
GL steel grit: although this type of hardness of the steel grit than GP steel grit - some high during shotblasting also loses its sharp edges - particularly suited to descaling and surface preparationg applications.
GH steel grit: such a high rigidity - in steel grit sandblasting assignments will always maintain edges and corners - to the formation of these rules - the surface of the wool is especially effective. GH steel grit shot peening machine for homework - should consider the construction requirements prior to price factor occasions (e.g. abrasion rolling processing). This steel grits are mainly used for compressed air shot peening equipment.
